Answer:

55.18 L

Explanation:

First we convert 113.4 g of NO₂ into moles, using its molar mass:

113.4 g ÷ 46 g/mol = 2.465 mol

Then we<u> use the PV=nRT formula</u>, where:

P = 1atm & T = 273K (This means STP)

n = 2.465 mol

R = 0.082 atm·L·mol⁻¹·K⁻¹

V = ?

Input the data:

1 atm * V = 2.465 mol * 0.082atm·L·mol⁻¹·K⁻¹ * 273 K

And <u>solve for V</u>:

V = 55.18 L

yarga [219]

Hello!

The part of the carbon cycle where humans had the greatest impact is the return of CO₂ to the atmosphere by burning of ancient organic matter.

The ancient organic matter is also called Fossil Fuels. Some Fossil Fuels are Petroleum and Coal. Fossil Fuels are used to power our society and are burned to provide energy for power plants and vehicles, and by burning them, Carbon Dioxide (CO₂) is produced, increasing the natural concentration of this compound in the atmosphere.

Have a nice day!

What reaction will take place if h2o is added to a mixture of nanh2/nh3? draw the products of the reaction (without sodium ion)?

Maru [420]

When sodium amide i.e. $NaNH_{2}$ reacts with water i.e. $H_{2}O$ results in the formation of sodium hydroxide i.e. $NaOH$ and ammonia $NH_{3}$ .

The chemical reaction is given by:

$NaNH_{2}+H_{2}O\rightarrow NH_{3}+NaOH$

Now, when ammonia i.e. $NH_{3}$ reacts with water results in the formation of ammonium hydroxide i.e. $NH_{4}OH$

The chemical reaction is given by:

$NH_{3}+H_{2}O\rightarrow NH_4OH$

Thus, the products of the above reactions are ammonia and ammonium hydroxide (without sodium ion).

The structures of the products are shown in figure (1): ammonium hydroxide and figure (2) ammonia.

Is it possible for two different compounds to be made from the exact same two elements? Why or why not? With a limited number of

daser333 [38]

Answer:

Yes. The two elements can combine to form different compounds.

Explanation:

Two elements can combine at different ratios.

Consider CO and CO₂. Both are made from carbon and oxygen. However, C and O combine at a 1:1 ratio in CO but at a 1:2 ratio in CO₂. CO is a fuel; it burns in the air. CO₂ does not burn in the air; it is used to put out fires and is found in extinguishers. CO and CO₂ are two distinct compounds.

There are many ways for the elements to combine with each other. As a result, the first twenty elements on the periodic table alone can produce a large number of compounds.
